PUNCH-PRESS.

To all whom it may concern. A

Be it known that I, Trroams F. Mourns, a citizen of the United States, residing at Waterford, in the county of Saratoga and State of New York, have invented certain new and useful Improvements in Punch- Presses, of which the following is a specification.

This invention relates to an improvement in punch presses, designed particularly for forming the openings in the gloves designed for the reception of the cooperating parts of the usual snap fasteners.

In forming such openings, it is absolutely essential that the openings in the respective parts exactly register in order that a smooth fastening of the glove may be had, and furthermore, it is highly desirable that the glove-openings for the reception of the male portion of the fastener be smaller than the openings for the reception of the female portions of the fastener, as such portions of the fastener correspondingly differ in size. The present punch press is also designed to provide openings for a particular type of fastener using holding spurs, wherein it is desirable that a considerable portion of the glove material, that is practically all such material, be left about the opening for the reception of the male portion of the fastener, in order that sufficient material is provided toinsure a proper grip of the spurs.-

The present punch press is therefore designed to simultaneously, punch the holesor openings in both sides of the glove opening, to insure absolute registry of such holes; form one such holelarger than the other; and project the material about one hole in a manner to provide the necessary material and at the proper place to receive the fasten ing prongs.

In the drawings Figure 1 isa perspective view of the improved punch press, with a glove in place.

Fig. 2 is a vertical section taken through the punch members.

Fig. 3 is a sectional detail illustrative of the completed punching operation with a glove in place.

Fig. 1 is a bottom perspective of one of the punches.

The improved punch press comprises a framework, including a base 1 having a pedestal 2 at the forward end thereof. The base extends forwardly of the pedestal and Specification of Letters Patent. Patented A 30 192 Application filed October 29, 1920.

Serial No. 420,466.

is provided with a bed-plate 8, on whichone section of the glove rests in the punching operation, this bed plate having openings if for the passage of the punches. A clampmg plate 5 overlies thebed-plate 3, being supported on an upright plate section formmg a positioning guide 6, such plate section 6 being secured to the forward ends of arms 7, which are pivotally supported at their rear ends by brackets 8 secured to the base 1. Springs 9 secured to the arms 7 and t9 the pedestal, normally influence the clamping plate in the upward direction, that 1s from the bed plate 3, and a stop 10 on the pedestal, limits the movement of the arm and therefore the clamping plate to a position above the bed plate somewhat in excess of that required for the introduction of a glove section between suchlates.

The pedestal is formed with forwardly extendlng flanges 11, in which in openings 12 are mounted the respective punches, which are preferably two in number in accordance with the usual number of snap fasteners for a glove. The punches are identical, each comprising a rod 13 slidably fitting the openings 12 and reduced at their lower ends to provide a point 14 having a long taper and a section 15 of uniform diameter above such tapered point. Each rod is normally held in an elevated position by a spring 16 coiledabout the rod and bearing between the lower flange 11 of the pedestal and a washer 17 secured on the rod. The reduced or point portion of the punch rod is provided with a clamping foot 18, preferably a cylindrical section surrounding the point with its lower edge serrated, as at 19. A spring 20 carries such foot and is coiled about the point and held to the rod proper, so that as the clamping foot reaches the clamping plate, it will'depress such plate for a clamping operation, the foot resting on the glove on such clamping plate, while the point will continue in movement for the punching operation.

7 A spacing stop 21 is pivotally secured on each arm 7, comprising a plate having a forwardly projecting and reduced extension 22, which projects forwardly of the guide 6, and with the extended portion of the plate proper forms a shoulder adapted to receive the glove at the junction of the wrist portions thereof, that is the meeting end of the hand opening edges to be provided with fas- Cir the openings to be formed by the punches. These spacing guides are arranged one at each side of the press, forming right and left hand guides for rightand left hand gloves, the pivotal mounting of such spacing guides permitting the guide not in use in the particular operation to be turned up out of the way.

A press bar 28 is pivotally supported between ears 24L at the rear of the base 1, and is provided with a head 24: to overlie the punches. A rearward projection of the bar 23 is formed with an opening to receive a foot lever 25, whereby the press bar and therefore the punches may be operated at will. A set screw 26 may be arranged in the pedestal for adjustment to limit the depression of the press bar, and therefore the extent of movement of the punches.

In use, a glove is positioned in the press, the meeting ends of the edges of the hand opening of the glove being arranged over the spacing guide, as shown, and the edges to be punched disposed, against the guide plate 6. One section of the glove is arranged on the bed plate 3 below the clamping plate, that is the glove section designed to receive the male portions of the fasteners, while the other section is arranged above the clamping plate,.tl1is latter being the glove section designed to receive the female portions of the fasteners. The foot lever 25 is operated to depress the punches. The clamping foot of each punch first engages the glove section overlying the clamping plate and then depresses the clamping plate onto the section of glove between such clamping plate and bed plate. Both glove sections are thus held against accidental movement, and the punch point, in the continued movement of the punch continues through the material. The tapered point enters the upper section of the glove and continues through the lower section. The length of such tapered point is, however, sufficient to pass entirely beyond the upper glove section, and partially through the lower glove section. This results in a large opening as 27 in the upper glove section, and a smaller hole 28 in the lower section, such larger hole being formed by the section 15 of the point, while the smaller hole is formed by a portion of the length of the tapered portion of the point. y reason of thistap'er; the material about the smaller hole on the remote surface or" the glove section will be depressed as in cone formation as at 29, thereby providing the necessary material for the proper holding of the spurs of the fastener parts.

It is of course understood that that section of the glove to receive the female portion of the fasteners is the uppermost sectionwhen the glove is fastened about the wrists, and that such is the uppermost section in the press. Through the use pf the spacing guide to limit the movement of the glove in one direction in applying the same to the press, and the guide 6 to form a positioning means for the edges of the glove sections, an absolute registry of the parts is secured without particular care or attention, and thus the holes for the fastener members will absolutely register, and the fasteners cooperate so that the glove will lie smooth when fastened.

It is to be particularly noted that the element herein desigiiiated as a punch does not EQYL' any por ion of the material from the glove in the punching operation, but that such element is primarily a perforator, initially forming a minute entrance opening through which the remaining operative length of the element is forced in the punching operation. As a result of this particu lar construction, the material corresponding to the area of the final opening is forced beyond one surface of such material as an integral projection, forming in effect a wall like extension beyond one surface of and corresponding to the opening formed. This extension is a highly important characteristic of the machineparticularly in the use of such machine with materials of a thin or yielding nature, in that through the provision of this integral extension of the mate rial beyond one surface thereof, thereis formed beyond such surface an excess of material which provides an additional thickness of material to receive the spurs and other fastenin elements of the clasp members to be used. Therefore in the specific-a tion and claims, the use of the term punch is intended to generally designate a perforation vvithout cutting any portion of the material therefrom' as distinguished from the usual punch wherein an opening is formed by cutting a prescribed area from the material.
